Story Before Rules
Rules exist to support the story, not control it. Narrative outcomes always take priority over mechanical complexity.

Built on Seven Principles.
Designed for Infinite Worlds.
Core7 ENGINE is more than a set of mechanics. It is a design philosophy built around seven guiding principles that keep stories moving, reward creativity and support meaningful play.
Common Sense Before Complexity
Practical judgement and sensible rulings are preferred over unnecessary layers of detailed mechanics.
Skills Grant Competence
Skills improve a character's chances of success. They do not define what a character is allowed to attempt.
Roll Only When It Matters
Dice are used when outcomes are uncertain and the result will meaningfully affect the story.
Consequences Matter
Every significant action should have an impact, creating new opportunities, challenges and story developments.
Support Creativity
Players and Gamesmasters are encouraged to think creatively, explore ideas and shape the world around them.
Keep the Story Moving
Momentum is more important than perfect rules interpretation. The game should never become trapped in procedure.
